"These nodes make the procedural workflow easy"

Extra Nodes:

Procedural Particle System with Forces Nodes: (New v2.4)

• It is an advanced Procedural Particle System based on the Simulation Nodes of Blender 3.6x, 4.0x, and 4.1x.

• It has 21 forces to control the dynamics of these particles and many advanced features (Sub-Steps, Collision, Stick, Hit, etc.).

• It has density-based particle emission, particle-particle collision, particle-geometry collision, particle-geometry stick, and many advanced features.

• It also comes with a Particle Tracer Node, Particle Action Node, and Particle Info Node (Demo Video).

Falloff Tracer Node:

• It generates lines based on any field's 2D/3D Curl or Gradient. You may also use Field Nodes for further control.

Memory Falloff Node: (New v1.1)

• It stores attribute value with time. The stored attribute can be animated with a Factor or Time Duration. It is based on the Simulation Nodes of Blender 3.6x, 4.0x, and 4.1x.

Field Nodes:

• There are 8 field nodes to generate fields based on Mesh, Curve, Curl Gradient, etc.

Falloff Nodes:

• 20 falloff nodes provide straightforward control over the field based on the falloff.

Mesh Nodes:

Utility Nodes:

There are utility nodes: Loop Node, Integration Node, Selection Based on Attribute, 3D Viewer Node, Vector Viewer Node, Index Viewer Node, Time Speed, and Guide Curves node (NEW, for Blender 3.5x or higher).

Bake

The Blender 3.6x (or higher) has the baking feature for the Simulation Nodes of the Geometry Nodes. To bake: Select the Object having the simulation nodes -> Physics Tab -> Simulation Nodes (Bottom) -> Press Bake. It will bake and store the cache next to the project file.

About

This tool is made with geometry nodes and can be used in Blender 3.3x, 3.4x, 3.5x, 3.6x, 4.0x, and 4.1x. The Procedural Particle System and Memory Falloff node are only for Blender 3.6x, Blender 4.0x, and Blender 4.1x.

License

You can use this tool in any of your projects (non-commercial or commercial).

You may not redistribute the geometry node group itself, for free or commercially.

Happy Noding... :)

• Removed unwanted Time-based Seed for Random attribute.
  

21/01/2024:

Procedural Particle System v2.3 updates:

• Fixed the motion blur issue for Continue Emission mode. It was related to Particle ID, now particles have a unique ID in any emission mode. This fix also simplifies the Particle Index. This might change the result for old files.
  
• Fixed the Set Point Radius warning for geometry that does not have points.
  

Procedural Particle System v2.3 updates:

• Added "Animated" option in Stick node. It can be enabled particularly for animated surfaces. This updates the Particle Position and Stick Axis.
  
• Added "Stick Axis" option in Rotation panel (new) to Stick node, which allows to rotate the stick particles w.r.t surface normal (or particle velocity) with the help of the Particle Rotation node or manually with Align Euler to Vector node.
• The Stick node now can handle multiple objects with UVMap that have the same name.
• Fixed the unwanted updation of normal for the Avoid in Stick node.
  

17/01/2024:
Released the Procedural Particle System v2.3 for the Extra Nodes (Geometry Nodes) for Blender 3.6, 4.0:
